Definitions

  • the invention relates to an adjusting mechanism for a motor vehicle seat, in particular an arrangement for clearance compensation for such transmissions, according to the preamble of patent claim 1.
  • the functional properties of these transmissions also depend very much on the exact matching of the spring force on the wedge segments with the coefficients of friction in the sliding bearing and on the contact surfaces of the wedge segments. This problem is solved in the known solutions in the way that the surfaces of the functionally relevant components have a very high quality. If the known transmission used for transmitting load torque, the wedge segments make themselves noticeable by a deterioration of the efficiency. In this case, the wedge segments increase the frictional torque in the bearing points.
  • the present invention has for its object to provide a variable, which ensures good performance with low construction costs.
  • the main features of the function here are the efficiency, a low idle drive torque and a backlash compensation, which makes the gearbox appear outwardly play.
  • a gearbox can be considered as free of play, if, under the condition that no actuation of the drive shaft takes place, between the parts to be rotated as torsionally rigid.
  • the invention provides in its most general form that a transmission shaft used as a bending spring via a split drive shaft introduces a spring force in the adjusting and thus braces the items of the transmission without play.
  • Fig. 1 - an arrangement of 2 adjusting gears, which are connected to a transmission shaft 7, as is customary for example for adjusting a motor vehicle seat back.
  • Fig. 2 - an exploded perspective view of a erfindungsgemäe field embodiment of a variable transmission. In the illustrated adjustment is a wobble gear.
  • FIG. 3 shows a section along the plane II according to FIG. 5.
  • Fig. 4 - a section as in Figure 3, but in an enlarged view of a single gear.
  • Fig. 5 - a section normal to the central axis I of Figure 2 through the toothing plane of the wobble mechanism.
  • FIG. 6 shows a representation similar to FIG. 1, but with a variant of the transmission shaft.
  • the adjusting gears are shown in their design as Weglehnenne Trents- adjustment for a motor vehicle seat.
  • two adjusting gear are arranged on the outer sides of the vehicle seat.
  • a seat-mounted gear part is designed as a lower part 1 and fixedly arranged on the seat part of the vehicle seat.
  • a rotatable transmission part is designed as a top part 2 and connected in each case on the outside with a backrest, not shown, of the motor vehicle seat.
  • the drive shafts of both adjusting gears are connected to a transmission shaft 7.
  • the adjusting gear with the lower part 1 and the upper part 2 is known as a so-called wobble gear.
  • the upper part 2 has for this purpose an internal toothing 2a, and the lower part 1 an outer toothing 1 a. Both teeth are in meshing engagement with each other and are guided by a drive shaft consisting of an inner part 3 and an eccentric part 4.
  • the inner part 3 is mounted in the upper part 2.
  • a passage 2b is formed on the upper part 2, in which a sliding bearing 9 is arranged.
  • the eccentric 4 is mounted on a slide bearing 8 in the lower part 1.
  • the center points of the bearing points of the eccentric part 4 and the inner part 3 are offset by the distance of the eccentricity e (FIG. 5).
  • the eccentric 4 is rotationally connected to the inner part 3.
  • the backlash of the variable transmission is created with the assembly of the transmission shaft 7 in the transmission.
  • the inner part 3 of the two-part drive shaft is in a torque transmitting connection with the transmission shaft 7.
  • a contour 3c is formed in the inner part 3, which ensures a positive connection with the transmission shaft.
  • the transmission shaft 7 is also in contact with the eccentric part 4 via a curved contact surface 4a.
  • the teeth of the teeth 1 a and 2 a are pushed into each other until they lie against each other without play.
  • the parts of the drive shaft, the inner part 3 and the eccentric 4 are moved within their bearing clearance in the sliding bearing in the direction of the forces F3a and F4a. Due to the forces F3a and F4a, the entire adjusting mechanism is braced, so that it is free of play. So that the force F7 can be introduced into the transmission shaft 7, a second bearing point for the transmission shaft 7 is required. If the transmission shaft 7 is prestressed into the unit consisting of the adjusting mechanism and the second bearing point, the forces F3a and F4a act on the adjusting mechanism the second bearing point the force F7. The distance between this second bearing point of the adjusting, the moment of inertia of the transmission shaft and the size of the bias decide the spring characteristics of the shaft, and thus the size of the forces F3a, F4a and F7.
  • FIG. 6 also shows an arrangement for a motor vehicle seat back.
  • the transmission shaft 7 has been replaced by the transmission shafts 8 and 9.
  • the transmission shafts 8 and 9 are positively connected by the connection members 10, so that torque can be transmitted between the transmission shafts.
  • the connecting elements 10 By the connecting elements 10, the transmission shafts 8 and 9 are mutually braced, so that the forces F3a and F4a rest in the adjusting and the adjusting gear are free of play.
  • the arrangement in Figure 6 has a greater variety of parts, the assembly of the transmission shafts 8 and 9 but initially done without a bias, so that the insertion of the transmission shafts in the adjustment will be easier to implement.
  • the bias voltage is applied by attaching the connecting elements 10.
  • the two transmission shafts 8 and 9 act independently of each other on each one adjusting.
  • the transmission may also be a planetary gear or variants thereof, e.g. the central planetary gear is moved.
  • the invention it is also possible to apply the invention to other transmissions.

Abstract

La présente invention concerne un mécanisme de réglage, en particulier pour un siège de véhicule, comprenant une partie supérieure et une partie inférieure qui sont pourvues de dentures reliées de manière à pouvoir être entraînées, un arbre d'entraînement qui entraîne de préférence la partie supérieure, ainsi qu'un arbre de transmission qui est solidaire en rotation. Le mécanisme de réglage selon cette invention est caractérisé en ce que l'arbre d'entraînement est constitué d'au moins deux pièces qui sont placées dans la direction radiale de manière à pouvoir se déplacer l'une par rapport à l'autre et en ce que l'arbre de transmission fait passer un couple dans les pièces de l'arbre d'entraînement.
